Keep Your Head Up: 'Text Neck' Takes A Toll On The Spine

"Text neck," the posture formed by leaning over a cellphone while reading and texting, is a big problem, according to the author of a newly published study in the National Library of Medicine.

Kenneth K. Hansraj, chief of spine surgery at New York Spine Surgery & Rehabilitation Medicine, says the bad posture can put up to 60 pounds of pressure on the upper spine — sometimes for several hours a day, depending on how often people look at their devices.
